1125-APMAT-CD4:多模态单细胞分辨率下CD4+ T细胞筛选平台

from 聊聊Sci

这篇研究介绍了一种名为APMAT-CD4的高通量分析平台,旨在克服检测和分析CD4+ T细胞时面临的技术挑战。该技术利用大规模的II类主要组织相容性复合体(MHC II)单链三聚体(SCT)库,能够同步分析单细胞水平的抗原特异性、TCR序列、转录组状态以及患者来源。研究人员通过对新冠病毒(SARS-CoV-2)和人乳头瘤病毒(HPV-16)的蛋白质组进行系统筛查,成功识别了多种关键的免疫原性抗原和功能性TCR。实验证明,该平台不仅揭示了病毒感染过程中免疫细胞的动态演变,还发现了具有临床转化潜力的癌症免疫治疗靶点。通过整合多维度的单细胞数据,该方法为精密疫苗设计和下一代TCR-T细胞疗法提供了强大的技术支撑。References:Zhang R, Qi J, McKasson M, Choi J, Gutierrez V, Brennan C, Hong S, Chour W, Ng RH, Xie J, Yuan D, Webster A, Sidhu SK, Anderson A, Chen D, Edmark R, Murray KM, Li S, McDonald C, Rowen L, Wang S, Rasheed Y, Su Y, Wagner JR, Chen JM, Nawaly K, Fu J, Duven A, Forman SJ, Song M, Priceman SJ, Brown CE, Ribas A, Wong DJ, Paulson KG, Drescher CW, Puig-Saus C, Goldman JD, Trimble CL, Heath JR.
